A man accused of killing his co-worker at a local Walgreens was found competent to stand trial. A judge made the announcement during a review hearing Friday afternoon. Joshua Johnson is accused of killing 17-year-old Riley Whitelaw in the breakroom at the Walgreens at Centennial and Vindicator nearly a year ago. Meanwhile, Johnson’s defense team objected to the results of the competency evaluation and requested another. The judge granted their request.
